Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-3 One embodiment of this utility model is a precision scribing pliers with an angle indicator, comprising a scribing ruler 1, a length adjustment block 7 slidably connected to the inner wall of the scribing ruler 1, an adjustment knob 6 threadedly connected to the top of the length adjustment block 7, a sleeve 14 fixedly connected to one end of the adjustment knob 6, a scribing head 15 threadedly connected to the inner wall of the sleeve 14, a locking knob 4 rotatably connected to the outer wall of the length adjustment block 7, a spring 5 slidably connected to the inner wall of the locking knob 4, and an adjustable mounting component provided at one end of the scribing ruler 1.

[0020] Specifically, the sleeve 14 can quickly replace the scribing head 15. The scribing head 15 used for scribing different workpieces is different. The sleeve 14 can quickly replace the scribing head 15. Depending on the characteristics of different scribing heads 15 and different workpieces, the distance between the scribing head 15 and the workpiece is also different. By adjusting the knob 6, the scribing head 15 can be moved to the appropriate position for scribing.

[0021] Reference Figures 3-4 The adjustable mounting components include a magnetic base 8, the top of which is rotatably connected to the inner wall of the scribing ruler 1. A chuck 10 is rotatably connected to the top of the magnetic base 8. A threaded rod 11 is fixedly connected to the surface of the chuck 10. A locking tooth 12 is rotatably connected to the surface of the threaded rod 11. A nut 13 is threadedly connected to the surface of the threaded rod 11. A suction cup 9 is threadedly connected to the inner wall of the magnetic base 8.

[0022] Specifically, the magnetic base 8 allows the device to be quickly fixed to the surface of a metal workpiece, while the suction cup 9 allows it to be quickly fixed to the surface of a smooth workpiece. The rotatable chuck 10 and rotatable teeth 12 can be rotated to a position that is convenient for clamping the workpiece, and can also be fixed on non-metallic or smooth surfaces, thus adapting to more workpieces.

[0023] Reference Figure 1 The inner wall of the scribing ruler 1 is provided with a guide rail, and the outer wall of the length adjustment block 7 is slidably connected to the guide rail.

[0024] Specifically, the guide rail can make the positioning of the scribing head 15 more precise, thus making the scribing more accurate.

[0025] Reference Figure 1 An angle meter 2 is fixedly connected to the top of the magnetic base 8.

[0026] Specifically, the angle gauge 2 enables the device to draw arcs of precise length and straight lines of precise angle.

[0027] Reference Figure 1 An angle needle 3 is fixedly connected to one end of the scribing ruler 1. The angle needle 3 is at a right angle to the scribing ruler 1 and rotates on the same axis.

[0028] Specifically, the angle needle 3 allows for a more intuitive reading of the angle, and the coaxial rotation makes the rotation of the scribing ruler 1 more precise.

[0029] Reference Figure 6 The bottom of the locking knob 4 has a protrusion, and the inner wall of the length adjustment block 7 has an L-shaped groove. The protrusion of the locking knob 4 is slidably connected in the L-shaped groove. There are multiple locking knobs 4, and the outer wall of the locking knob 4 is rotatably connected to the inner wall of the angle gauge 2.

[0030] Specifically, by pressing and rotating the locking knob 4, the bottom protrusion is locked inside the L-shaped groove, achieving the effect of quickly fixing a specified angle and length.

[0032] Specifically, the adjusting knob 6, connected by a thread, allows for more precise height adjustment of the sleeve 14, and the slide will keep the sleeve 14 stable, preventing deviation during the scribing process and ensuring accurate scribing.

[0033] Reference Figure 5 The bottom of the magnetic base 8 has a threaded hole, and the top of the suction cup 9 is threaded into the threaded hole.

[0034] Specifically, the suction cup 9 can be quickly installed in the threaded hole or removed to allow for quick replacement of the compatible base, saving time.

[0035] Working principle: When using this device, first select the scribing head 15 according to the material to be scribed, and install it inside the sleeve 14. Then, select the base to assist in fixing the device according to the material. Place the magnetic base 8 in a suitable position and adjust it to the appropriate position by using the chuck 10. Tighten the nut 13 at the bottom of the threaded rod 11 upward to move the chuck teeth 12 upward, thereby fixing the chuck 10 and chuck teeth 12 to the workpiece surface. Then, rotate the scribing ruler 1 to drive the rotation of the angle needle 3. Adjust the scribing angle by moving the angle needle 3 on the surface of the angle gauge 2. Then, press and rotate the locking knob 4 to fix the angle. Rotate the adjusting knob 6 to move the sleeve 14 up and down to adjust the scribing head 15 to the appropriate position in contact with the workpiece. Scribing is done by moving the length adjusting block 7. If scribing an arc line, press and rotate the locking knob 4 on the outer wall of the length adjusting block 7 to fix the length. Rotate the locking knob 4 on the surface of the angle gauge 2 in the opposite direction to allow the scribing ruler 1 to rotate.
